Im not fond of these ne items on traditional rods, but I got to see one today for a SBC!!!! Very intresting unit. if you havent seen these they have a shaft aka plug that has a gear on it for the dist shaft. the a set of coils like on new model cars. and a simple plug. WOW if I had a closed car Id think about it..there only $750.00 plus tax and shipping hahahahaah NO WAY baby
